New York City is terrorized by a gang led by the so-called Queen of Crime. When she and her gang attempt to rob the National Trust Bank, the Human Torch and Toro are there to stop her. However, when the gang is rounded up, reinforcements arrive and begin gunning down police creating enough of a distraction for the Queen of Crime and most of her men to escape. Questioning the surviving gang members that were captured, the Torch and Toro learn that they are madly in love with her and will not talk.

The two heroes return to their apartment where Toro finds a note from his friend Jimmy Winters asking him to visit on a matter of importance. After Toro leaves, the Queen of Crime appears in the Torch's apartment and offers him a chance to join her in her criminal empire. When he refuses he gets a phone call from Toro who tells the Torch that he walked into a trap and is now prisoner of the Queen of Crime. The Queen of Crime then leaves an address with the Torch, telling him he has to make up his mind, if he refuses than she will kill his partner.

With no other choice, the Torch goes to the address and is tied up with asbestos rope and brought before the Queen of Crime. Seeing Toro is similarly bound he gives the boy visual cues to be ready to attack. The Torch "agrees" to join the Queen of Crime and convinces her to remove his bonds. After the Queen details her armored car robbery plan, both he and Toro then flame on, the Torch freeing Toro and sending the crooks on the run. However they are tricked into flying into an asbestos lined room with collapsing walls. However the pair get out by prying off a roof vent. They then race after the Queen of Crime and her gang, forcing the crooks to break off their heist, but they get into a car accident as they try to flee. The Torch then visits the recovering Queen of Crime in the hospital telling her this is just another round before the final one of her career.

A commission of doctors led by Dr. Zodus meet to discuss the experiments of Dr. Bradley, and find that his attempts of keeping the human body alive without a head too grisly to continue and strip him of his medical license. Bradley leaves the commission vowing to get revenge against them. Soon from his secret lab, Bradley continues his experiments, kidnapping human test subjects and discarding their dead bodies when his experiments fail. Soon his experiment is an apparent success and he called Dr. Zodus' assistant to come to his lab where he shows off his Headless Man, telling him that he will go out and tell the world that his experiment is a success.

Meanwhile, the Sub-Mariner and Betty Dean meet to go to a medical dinner being hosted by Dr. Zodus and his colleagues. During the banquet, Dr. Rogers is attacked and killed by Bradley's Headless Man. Hearing Rogers' dying screams the Sub-Mariner rushes to his aid and attacks the Headless Man, but the creature knocks him out and flees the scene. Namor goes outside to try and track the creature but finds no trace of it. He runs into Zodus' assistant who tells him about Bradley's revenge scheme. Namor then goes to Bradley's lab to find that he has already fled, leaving a mocking note for the police about his future success.

The Sub-Mariner and the police then question Kenyon, one of the doctors who Bradley hates and he believes he'll be the next victim. However, when Namor searches Kenyon's room he finds a note that suggests that Kenyon did not like Dr. Zodus either. Namor rushes to Zodus' home and catches the Headless Man strangling Zodus to death. When Namor attempts to stop the creature from killing Zodus, he is sprayed with a knock out gas. With Zodus dead, the Headless Man then kidnaps his daughter Helen and flees.

Reviving, Namor follows after the Headless Man and deduces that he has fled to a nearby launch that is speeding away. Smashing into the ship, Namor confronts Bradley and the Headless Man, but is forced to stand down when Bradley threatens to kill Helen. Namor is then knocked out by Bradley, and both he and Helen are placed in an air and water tight concrete coffin. They are then brought to Devil's Rock and dumped overboard. Revived, Namor and Helen try shift their concrete prison to land on the jagged rocks at the bottom of Devil's Rock, puncturing the concrete and allowing water to flow in. With his strength revitalized, Namor breaks free and brings Helen to safety aboard a Coast Guard cutter.

Meanwhile, aboard Bradley's ship the Headless Man turns on his master and attempts to kill when when Namor smashes in. Knocking out Bradley and knocking off the Headless Man's fish-bowl Namor easily subdues the "monster" revealing him to be Kenyon in disguise. With the authorities arrival, Kenyon explains that he joined up with Bradley to kill Zodus in order to steal his new formula. When he succeeded he decided that Bradley was too dangerous to keep alive and attempted to kill him as well.

In Buenos Aries, American government agent Ted Banning is heading to the airport with a list of escaped Nazi war criminals. In his taxi he is confronted by men who know his mission and knock him out. The next day in New York, Madeline Joyce meets with government officials and learns about Banning's disappearance. Suspecting that these escaped Nazi's may be planning World War III, the government asks Madeline to go to Brazil as Miss America and track down that list and stop any Nazi activities in the area, using her civilian identity to pose as an idle rich tourist.

To this end, Madeline goes to a downtown dress shop to purchase new clothing, bragging about her trip to South America. This is overheard by a woman named Wyatt Varnham. Varnham pays a visit to Madeline at her apartment, and asks her to deliver a gold and topaz bracelet to her sister, whom Varnham tells her is living in Buenos Aries, and Madeline agrees. As Madeline heads to Laguardia airport she notices that she is being followed.

Aboard the plane she notices how three passengers: James Ilse, his wife, and Peter Carr and conversing as though they have met for the first time, but spies them passing notes to each other with her compact mirror. Carr, having become attracted to Madeline Joyce falls for her attempt to get to know him when she drops her lipstick on the floor. Carr introduces himself and explains that he is a writer from California who is going to Buenos Aries to research his next book. The two talk for the reminder of the flight with the Ilse couple taking close watch to how Carr is getting along with the girl.

After they land, Peter Carr asks Madeline to join him at an evening dance and she accepts. As they sign in, Madeline notes that Peter's gloves are made in Belgium and that they have the initials "L.R." stamped into them, making her suspicious of his character. As Madeline gets ready for the dance, she swoons over how attractive Peter is, but worries if she can trust him. Meanwhile, Peter is putting a gun into his coat just in case, while two men meet at the airport, one of them reporting to the other that Madeline Joyce has arrived in the country and that everything is going according to plan.

However, the cell is dry enough for Toro to flame on and he uses his flame to kill the lizards and break them free.

Soon the authorities arrive to rescue the stranded youths and take the gang into custody.
